ROCKLAND — Oceanside High School, 400 Broadway, presents “Elf Jr. The Musical” Wednesday, Thursday and Saturday, Dec. 14, 15 and 17, at 7:30 p.m. and Sunday, Dec. 18, at 2 p.m.

Based on the New Line Cinema hit film, “Elf Jr.” features songs by Tony Award-nominees Matthew Sklar and Chad Beguelin, with a book by Tony Award-winners Thomas Meehan and Bob Martin.

Buddy, a young orphan, mistakenly crawls into Santa’s bag of gifts and is transported to the North Pole. The would-be elf is raised, unaware that he is actually a human, until his enormous size and poor toy-making abilities cause him to face the truth. With Santa’s permission, Buddy embarks on a journey to New York City to find his birth father and discover his true identity. Faced with the harsh reality that his father is on the naughty list and that his half-brother doesn’t even believe in Santa, Buddy is determined to win over his new family and help New York remember the true meaning of Christmas.

This modern-day holiday classic features plenty of large ensemble numbers with every young performer embracing their “inner elf.”

Tickets on sale at the door are $8 for adults, $5 for seniors and students.
